4.4.1 Preservation
Before preservation, check that surfaces of metal devices do not have corrosion,
clean the surfaces using brush or cloth; apply cleaning products if necessary. Time between

Before placing the silica gel inside the packaging, bag it, and then mark its weight
and brand. Weight of a single bag shall not exceed 1 kg.
After sealing the packaging joints, press out the cover manually to remove excess
air from the packaging, make sure it is tight and seal the remaining holes.
Check visually that packaging is intact, and joints are sealed. Holes, unsealed spots,
